Embodiment 1

[0034] The first embodiment of the present invention provides a prefabricated module for constructing deformation joints, such as figure 1 As shown, it includes an L-shaped formwork 1, and the L-shaped formwork includes a horizontal wall 10 and a vertical wall 13; it also includes angle steel 2, anchors, protective covers 5 and several accessories, which are prefabricated and assembled in a factory and packed by a packing box 17 Transported to the construction site for direct use. The accessories include a steel pressure plate 18, a stainless steel force transmission plate 9 with a width smaller than that of the deformation seam, and a plurality of polyethylene protective plates 8 with the same width as the deformation seam for filling the deformation seam. The L-shaped mold plate 1 is used as a formwork when pouring deformation joints, the main body of the mold plate is “L” shaped, and the design standard length of each section of the mold plate is 600 mm. The lower part has...

Embodiment 2

[0036] The second embodiment of the present invention provides a waterproof construction method for deformation joints based on the prefabricated modules for constructing deformation joints in Embodiment 1, including:

[0037] Firstly, before the deformation joint is poured, the prefabricated modules of the deformation joint are accurately misplaced and positioned on both sides of the joint, and clamped at the joint; the end of the anchor bar on the angle steel is spot welded on the steel bar;

[0038] Next, set up the formwork, pre-embed the XPS formwork of not less than 45kg / m3 in the joint, and pour concrete on both sides of the deformation joint;

[0039] When supporting the mold at the seam of the side wall, accurately misplace the positioning, and clamp the mold plate 1, the protective cover 5, the embedded parts and the upper cover of the inner package together in the side mold, and only expose the foot rib at the lower part of the mold plate 11 and 12 and their own har...

Abstract

The invention discloses a prefabricated module for constructing a deformation joint and a deformation joint waterproof construction method. The prefabricated module comprises an L-shaped mold disc, angle steel, a protection cover, a stainless steel force transfer plate, a polyethylene protection plate and a steel pressing plate; the L-shaped mold disc is used as a mold plate during deformation joint pouring, two foot ribs perpendicular to the horizontal wall are arranged on the lower surface of the horizontal wall of the L-shaped mold disc, and a rigid polyurethane foam strip is arranged between the two foot ribs; the angle steel is arranged in a side surface space formed by the foot rib located on one side of the vertical wall and the mold disc, one side of the angle steel and the bottomsurface of the mold disc are anchored in advance through an anchoring part, and the other side of the angle steel abuts against the adjacent foot rib; and the protection cover is arranged above the mold disc, and a part of the protection cover covers and is clamped with the bolt for fixing the angle steel. According to the prefabricated module for constructing the deformation joint and the deformation joint waterproof construction method, the deformation joint structure is modularized, sealed, subjected to pressure-bearing splitting and then recombined, so that the deformation joint structureis more convenient to construct and good in leakage prevention and pressure resistance.

Description

technical field [0001] The invention relates to the technical field of building waterproofing, in particular to a prefabricated module for constructing deformation joints and a waterproof construction method for deformation joints. Background technique [0002] Underground engineering deformation joints bear high hydrostatic pressure. Most of the traditional structures are stereotyped waterstops, including central type, external type, and detachable type, and the success rate is not high. These projects rely on physical extrusion to achieve sealing, often due to the multi-directional deformation, the extrusion force at the local gap is different, resulting in leakage. [0003] Aladdin and Pegasus, which were introduced many years ago, have the problem of acclimatization: the main reason is that the seam retention process of civil engineering is generally poor, and it is difficult to achieve the minimum straightness. Therefore, in engineering practice, it is often necessary...
